- This paper determines for the first time an iterative process required to obtain valid high-angular resolution data to measure strain in metallic polycrystals by employing a crystal plasticity approach to overcome a major limiting assumption in the experimental validation. This insight is critical and not previously considered; this paper illustrates the balance needed between modelling and experimental validation not only for materials behaviour but to develop robust lifing models for industry. This research supports on-going lifing activities at Rolls-Royce plc (mark.hardy@rolls-royce.com; david.rugg@rolls-royce.com) and has significant impact both in industry and academia in developing robust protocols for validation.
